Great game! I like that the helpful objects (slimes and ledges) are color coded. However, the boss… well, kinda just exists. You don’t even fight the thing, just hit some spheres while it sits there dropping bones. I feel like you could’ve done something more interesting with the boss - for example, maybe it chases you up part of the tower, thus adding to the theme with a pseudo- time limit. Or for a more reasonable idea (given what you already have), you could’ve made it so that you have to climb up to the boss while dodging its bones.
